.To all whom it may concer/a.' i

Be it -known that we, CHARLES E. BALL and SAMUEL H. BALL, both citizensof the.

linited States, andresidents of Turlock, in the county of Stanislaus,and Livingston, in the county of Merced, State of California, haveinvented certain new and useful l'mproveuicnts in, Scrapers,of which thefollowing is a specification. y

Our invention relates primarily to a scraper such as is used forroadconstruction. land leveling, limited to any particular work or class ofwork but is equally adaptable for any use -15 which requires the movingof earth or soils, particularly where it is desired or necessarytomove'the same for any considerable dis.- tance. Heretofore, in thelhauling of earth for 20 any distance, such as in road construction andthe like, it has first been necessary to shovel the same into dump orother wagons, haul the same to the desired'place of deposit, then dumpthe same and then use 5 shovels to spread the same. l lt is the objectof our inventionl to provide a' scraper or Scrapers mounted on aframe.sup orted at a suitable distance by wheels an carrying mechanismwhereby the Scrapers (one or more) may be lowered and loaded in theusual manner and lthen elevated and transported to the desired place ofdeposit, a suitable gate being provided to prevent the accidentalspillage of the load, and then dumped by tipping in 'the usual manner,suitable mechanism being provided to control the angle towhich the bowlis tipped, whereby-the load may be deposited in one place or may bespread to a level as desired; Other objects and advantages will appearhereinafter Yand, while we have shown and i will describe the 4preferredform of our invention, we wish it specifically understood that we do notlimitourselves to such preferred form butthat various changes andadaptations may be made therein without departing from the spirit of ourinvention.

Referring tov the drawings our Ydevice comprises a substantiallyrectangular frame' 10 supported at its front end upon a pivotal axle 11,which axle is supported at each end by wheels 12. Extending transverselyof frame 10, at a distance from its rear end, is an axle 13, supportednear each end byl bearings 14 secured to the upper face of frame 10, andrevolubly mounted upon each end of axle 13 are. the rear wheels 15.Wheels 15 are provided with suitable differential devices 16 of any ofthe well known constructions suitable for this purpose.

Extending upwardly from each side of frame 10 are members 17 and 18provided with oppositely positioned bearings 19v and 20 and revolublymounted in these bearings` are the-bowl elevating shafts 21 and 22.Rigidly mounted upon one of the ends of shafts 21 and 22 are bevel gears23 and 24, which are in mesh with pinion gears 25 and 26 loosely mountedupon an operating shaft 27 Shaft 27 is revolubly mounted in bearings 28extending outwardly from member 17. Extending transversely betweenmembers 17 and 18, revoluble therein, is a driving shaft 29 upon one endof which is rigidly mounted a bevel gear 30'which gear meshes with apinion gear 31 rigidly mount,- ed upon shaft 27. Rigidly mounted uponshaft 29, near the inner side of member 17, is a sprocket wheel 32 whichwheel is connected by a 'chain 33 to a sprocket wheel 34E 10o rigidlymounted upon axle 13, whereby when said axle 13 is rotated shafts 27 and29 are also rotated. Slidably but relatively non-revolubly mounted uponshaft 29, between the opposed faces of pinion gears 25 10e and 26, is aclutch member 35 the ends of which are provided with clutch jaws 36 and37 which jaws are adapted'to be brought into engagement with the clutchjaws 38v and 39 of pinion gears 25 and 26 respec- 110 tively tov causeshafts 21 and 22 to rotatein wardly reverse directions. Rigidly mountedupon the other ends of shafts 21 and 22 are brake drums 40, andsurrounding said drums 40 are brake bands 41. Asbest shown in Figs. 6and 7, one end of bands 41 are rigidly connected to a bracket 42extending Aout- Y from member 18 and the other end lies beneath the endof a flexible member 43 also extending outwardly from the outer side ofmember 18. ExtendingA between the free ends of brake bands 41 is a coilspring 44 which acts to separate said ends when pressure is releasedfrom member 43. Extending upwardly from member 18 is an angular bracket45 in which is slidably mounted a push rod 46 the lower end of l-whichis l.loosely mounted in an aperture intermediate the free endso'fvmember 43. The lower end of rod 46 is threaded and is provided witha nut 48'by means of which the movement of bands 41 is adjusted. A

` stud 49 connects the ends of bands 41 and bracket 42 and then extendsupwardly and its free end passes through apertures in the ends ofmembers 43 and the other end of bands 41. Pivotally connected to theupper ends of rods 46 is one end of a link 50 the other end of whichI ispivotaly connected to` the upper end of a lever 51. Lever 51 has itslower end rigidly connected to a shaft 52 pivotally mounted at its endsin members 17 and 18. The other end of shaft 52 is provided with anupstanding lever 54 on end of bar 58 is pivotally connected to av link58 loosely mounted upon the forwardshaft 52. Link '58 is cnnectedby a-link 59 to an operating lever 69 pivotally mounted at its lower end inframe 10. The forward shaft 52 is connected by a link 7 0@ in a similarorany other suitable Amanner to an released.

operating lever pivotally mounted at the A side'of lever 69. It will benoted that when the operating mechanism just described is in its neutralposition the brake band will be in its operative position and that'asthe op.

erating handles are moved to `bring. either en d of the clutch intoengagement' with the respective pinion gear, the brakevwill be Rigidlymounted upon shafts 21 and 22, near the inner sides of members 17 and18, are spur gears 71 and 72 which are in operative engagement with theteeth 73 of the bowlv elevating members 74. Loosely mounted uponshaft's21 and 22, at each side of gears 71 and 72, are .plate's75 and 76which plates straddle bars 74 and have reyolubly mounted in their freeends rollers 7 7 which bear against the outer faces of bars 74 to holdthe'same in operative engagement- -with the spur gears 71 and 72.

Pivotally mounted upon the lower ends of bars 74 are-the scraper bowls78 and 7 9. f

Extending from the outer sides of bowls 78 and 79to the inner sides offrame'10 are links 80 and 81. Pivotally connected to the outer sides ofbowls 78 and 79, at the Arear of the upper edges thereof, are theretaining members 82. As shown in Fig. 3, members 82 extend upwardly andforwardly at an angle and have theirfree ends widened and in thesewidened lends are provided elongated -openings 83 at the upper ends ofwhich studs are engaged .by the top of said edges as the bowl is movedupwardly, thereby swinging the free ends of members 82 upwardly andreleasing the 1same from the locking stud 85 and permitting the bowls totip forwardly. -Pivotally mounted at one end upon the inner faces of thesides of the bowls, near the top edges thereof, are arms 87 which curveforwardly and downwardly and havemounted on heir forward ends the gate88 which norma ly acts to close the front open end of the A{bowls.Extending outwardly from the outer face of frame 10 is a stud 89over-which pass the arms 87 and which serves to Vopenor elevate the gateas the bowls are moved downward to their loading position and also asthe bowl is tipped to its dumpin position.

In the operation o lour device the parts will normally lie in thepositions shown in Figs. l, 2 and 3 of the drawings.' As the device 1spropelledfalong the ground when it is desired 'to operate tliescraperbowls the operating handle will be moved forwardly, thereby causing theforward ends of the clutch members to engage the clutch portionsof theforward beyel piions and at the sa'me time releasing the brake whichwill permit. the bowls Vto be lowered the desired distance, at whichtime the operating handle will be returned to its normal verticalposition. i When thebowls are loaded tb the desired amount the operatinghandle will be moved rearwardly, thereby bringing the rearmost -end of`the clutch membersiinto engagement -'with the rear'- most bevel pinions,whereby the bowls are elevated a suiicient distance above the roundto'clear the same, when the operatmg'handle is :again returned tonormal, at

the same time setting. the brakes to hold the bowls in their elevatedpositions. When it is desired to dum the lbowlsv the operating handleagain emoved rearwardly an iso p55*" verse shafts adapted torotate saidtransthe bowls elevated until the top ofthe bowls engage studs 86 andelevate members 82,

v thereby releasi-ng recesses 84 from the lockto operatively engage saidspur gears,

ing studs 85, which permits the front ends of the bowls to tipdownwardly, at `the samev time arms 87, engaging stud 89, will be heldin their elevated position, thereby permitting the front endsof thebowls to fall away from gate 88 permitting the contents to pass out.When it is desired to spread -a longitudinal shaft journalled in saidframe ;a pair of bevel gears loosely mounted on said shaft for each ofsaid first mentioned gears, in mesh therewith; a clutch' member slidablybut non-revolubly mounted on said shaft between each pair ofV said bevelgears; means to move either one of said clutches to engage either one ofeach pair of bevel gears; spur gears rigidly mounted upon saidtransverse shaft, one at each end thereof; a scraper bowl foreach ofsaid shafts; a rack pivotally mounted at its lowerend on each side ofsaid bowls to extend upwardly and having teeth adapted whereby when saidtransverse shafts are rotated said bowls will be adjusted vertically; anloperating shaft mounted trans versely in said frame intermediate saidfirst mentioned transverse shafts; an operative connection between saidlast transverse shaft and said longitudinal shaft; an operativeconnection between said last transverse 'shaft and the aXle of saidframe; a brake Y drumon the ends of said first transverse4 shafts;braking means mounted on -said frame adapted for operative engagementvwith said brake drums; and means carried by said 'frame for operatingsaid clutches and releasing vsaid braking means synchro-y nously. l
